| Subject: mtd: atmel-quadspi: disallow building on ebsa110 |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| commit 2a9d92fb3a1282a4659f1bb6d5684018846537b7 upstream. |
| |
| I ran into a link-time error with the atmel-quadspi driver on the |
| EBSA110 platform: |
| |
| drivers/mtd/built-in.o: In function `atmel_qspi_run_command': |
| :(.text+0x1ee3c): undefined reference to `_memcpy_toio' |
| :(.text+0x1ee48): undefined reference to `_memcpy_fromio' |
| |
| The problem is that _memcpy_toio/_memcpy_fromio are not available on |
| that platform, and we have to prevent building the driver there. |
| |
| In case we want to backport this to older kernels: between linux-4.8 |
| and linux-4.20, the Kconfig entry was in drivers/mtd/spi-nor/Kconfig |
| but had the same problem. |
